BioCryst Presents New Real-world Evidence Showing Significant and Sustained Reductions in HAE Attack Rates in Adolescents and People with Severe HAE Following Initiation of ORLADEYO® (berotralstat)

Core Insights - BioCryst Pharmaceuticals announced significant real-world evidence demonstrating the effectiveness of ORLADEYO (berotralstat) in reducing hereditary angioedema (HAE) attack rates in adolescents and individuals with severe HAE over an 18-month follow-up period [1][3][7] Group 1: Study Findings - The study presented at the ISPOR 2025 conference showed that patients experienced significantly lower HAE attack rates while on ORLADEYO, with a reduction from a baseline of 7.78-8.23 attacks/month to 1.24-1.90 attacks/month [10] - Specifically, patients had 6.25 fewer attacks/month at 12 months and 6.43 fewer attacks/month at 18 months after starting ORLADEYO [10] - Adolescents aged 12-17 years also showed significant reductions, with 1.56 fewer attacks/month at 12 months and 1.85 fewer attacks/month at 18 months [10] Group 2: Patient Population - The findings were based on a retrospective pre-post study involving 56 U.S. patients with C1-inhibitor deficiency and 99 U.S. adolescents with HAE [5][6] - The results indicate that ORLADEYO is effective across different age groups and severity levels of HAE, providing confidence to both physicians and patients [3][7] Group 3: Product Information - ORLADEYO is the first and only oral therapy specifically designed for the prophylaxis of HAE attacks in patients aged 12 years and older, functioning as a plasma kallikrein inhibitor [8][9] - The therapy is administered as a once-daily capsule, which works by decreasing the activity of plasma kallikrein to prevent HAE attacks [8]
